ftwdt010_wdt: move header to include/faraday and enhance
1. Move header to include/faraday 2. Fix include path in ftwdt010_wdt.c 3. Fix function prototype and declaration to - ftwdt010_wdt_settimeout - ftwdt010_wdt_reset - ftwdt010_wdt_disable 4. Add "#if definde (CONFIG_HW_WATCHDOG)" let user have flexibilty to choose which better to his product. Signed-off-by: Macpaul Lin <macpaul@andestech.com>
